              ------------
shares of the Corporation shall be represented by certificates signed by the
President or a Vice-President and the Secretary or an Assistant Secretary, and
may be sealed with the seal of the Corporation or a facsimile thereof.  The
signatures of such officers may be facsimiles if the certificate is
countersigned by a transfer agent, or registered by a registrar, other than the
Corporation itself or an employee of the Corporation.  If an officer who has
signed or whose facsimile signature has been placed on such certificate ceases
to be an officer before the certificate is issued, it may be issued by the
Corporation with the same effect as if the person were an officer on the date of
issue.

          At a minimum each certificate of stock shall state upon its face:

               (a) the name of the issuing Corporation;

               (b) that the Corporation is organized under the laws of the State
of Alaska;

               (c) the name of the person to whom issued;

               (d) the number and class of shares and the designation of the
series, if any, which such certificate represents; and

               (e) if the Corporation is authorized to issue more than one class
of shares or different series within a class, the designations, relative rights,
preferences, and limitations applicable to each class and the variations in
rights, preferences and limitations determined for each series, and the Board of
Directors's authority to determine variations for future series, summarized
either on the front or back of the certificate. Alternatively, each certificate
may state conspicuously on its front or back that the Corporation will furnish
the shareholder this information upon written request and without charge.

          In case of any mutilation, loss or destruction of any certificate of
stock, another may be issued in its place on proof of such mutilation, loss or
destruction.  The Board of Directors may impose conditions on such issuance and
may require the giving of a satisfactory bond or indemnity to the Corporation in
such sum as they might determine or establish such other procedures as they deem
necessary.

          (2) Shares without Certificates:  The Board of Directors may authorize
              ---------------------------
the issuance without certificates of some or all of the Corporation's classes or
series of shares.  Within a reasonable time after the issuance or transfer of
shares without certificates, the Corporation shall send the shareholder a
written statement giving the information required by the Alaska Corporations
Code to appear on stock certificates.

books of the Corporation, kept at the registered office of the Corporation or at
its principal place of business, or at the office of its transfer agent or
registrar.  The Board of Directors may, by resolution, open a share register in
any state of the United States, and may employ an agent or agents to keep such
register, and to record transfers of shares therein.

               (b) Shares of stock shall be transferred by delivery of the
certificates therefor, accompanied either by an assignment in writing on the
back of the certificate or an assignment separate from certificate, or by a
written power of attorney to sell, assign and transfer the same, signed by the
holder of said certificate.  No shares of stock shall be transferred on the
books of the Corporation until the outstanding certificates therefor have been
surrendered to the Corporation.

          (4) Registered Owner:  Registered shareholders shall be treated by the
              ----------------
Corporation as the holders in fact of the stock standing in their respective
names and the Corporation shall not be bound to recognize any equitable or other
claim to or interest in any share on the part of any other person, whether or
not it shall have express or other notice thereof, except as expressly provided
below or by the laws of the State of Alaska.  The Board of Directors may adopt
by resolution a procedure whereby a shareholder of the Corporation may certify
in writing to the Corporation that all or a portion of the shares registered in
the name of such shareholder are held for the account of a specified person or
persons.  The resolution shall set forth:

               (a) The classification of shareholder who may certify;

               (b) The purpose or purposes for which the certification may be

closing of the stock transfer books, the date within which the certification
must be received by the Corporation; and

               (e) Such other provisions with respect to the procedure as are
deemed necessary or desirable.

          Upon receipt by the Corporation of a certification complying with the
procedure, the persons specified in the certification shall be deemed, for the
purpose or purposes set forth in the certification to be the holders of record
of the number of shares specified in place of the shareholder making the
certification.

          (5) Consideration for Shares:  Consideration for the issuance of
              ------------------------
shares may be paid, in whole or in part, in money, in other property, tangible
or intangible, or in labor or services actually performed for the Corporation.
Shares may be issued for consideration at a

                                       5


value fixed from time to time by the Board of Directors. A certificate may not
be issued for a share until the share is fully paid.

          (6) Fractional Shares or Scrip:  The corporation may by action of its
              --------------------------
Board of Directors:  (a) issue fractional shares which shall entitle the holder
to exercise voting rights, to receive dividends thereon, and to participate in
any of the assets of the Corporation in the event of liquidation; or (b) issue
scrip in registered or bearer form which entitles the holder to receive a full
share upon the surrender of such scrip aggregating a full share, but shall not
entitle the holder to exercise voting rights, to receive dividends, or to
participate in liquidation unless otherwise provided in the scrip.

          (7) Shares of Another Corporation:  Shares owned by the Corporation in
              -----------------------------
another corporation, domestic or foreign, may be voted by such officer, agent or
proxy as the Board of Directors may determine or, in the absence of such
determination, by the President of the Corporation.

                                   ARTICLE IV

                               Board of Directors
                               ------------------

          (1) Number and Powers:  All corporate powers shall be exercised by or
              -----------------
under the authority of, and the business and affairs of a Corporation shall be

seven (7) persons who shall be elected for a term of one year, and shall hold
office until their successors are elected and qualified.  Directors need not be
residents of the State of Alaska or shareholders of the Corporation.  In
addition to the powers and authorities by these Bylaws and the Articles of
Incorporation expressly conferred upon it, the Board of Directors may exercise
all such powers of the Corporation and do all such lawful acts and things as are
not prohibited by statute or by the Articles of Incorporation or by these Bylaws
or as directed or required to be exercised or done by the shareholders.

          (2) Change of Number:  The number of directors may at any time be
              ----------------
increased or decreased within the limits stated in this paragraph by amendment
of the Corporation's Articles of Incorporation or these Bylaws or by action of
the Board of Directors or shareholders under the special provisions of an
article or bylaw adopted by the approval of the outstanding shares, provided
that if the Board of Directors is authorized by the Articles of Incorporation or
Bylaws to change the number of directors, whether by amending the Bylaws or by
taking action under the specific provision of an article or a bylaw adopted by
the approval of the outstanding shares, the amendment or action shall require
the vote of a majority of the entire Board of Directors.  In no event shall a
decrease in the number of directors have the effect of shortening the term of
any incumbent director.

          (3) Election:  At the first annual meeting of shareholders and at each
              --------
subsequent annual meeting, the shareholders shall elect directors to hold office

elected to fill a vacancy, shall hold

                                       6


office until the expiration of the term for which elected and until a successor
has been elected and qualified.

          (4)  Vacancies:
               ---------

               (a) Except for a vacancy created by the removal of a director,
vacancies on the Board of Directors may be filled by a majority of the directors
then in office, whether or not less than a quorum, or a sole remaining director.

               (b) Vacancies occurring in the Board of Directors by reason of
removal of directors may be filled only upon the approval of the shareholders.

          (5)  Removal of Directors:
               --------------------

               (a) At a regular or special meeting for which proper notice has
been given, any or all of the directors may be removed without reason if the
removal is approved by the outstanding shares, subject to the following:

                   (i) if the Corporation has 500 or more holders of record
entitled to vote on the removal and election of directors, written or printed
notice of intention to seek removal under this section shall be delivered either
personally or by mail to each shareholder of record entitled to vote at the
meeting and if notice of intention to seek removal under this section is

                       (A) delivered to the President or Secretary of the
Corporation at least seventy-five days before the date of the annual meeting it
shall be included on the notice stating the place, day, and hour of the annual
meeting without cost to the shareholder seeking removal; or

                       (B) not timely under (A) of this paragraph the
shareholder seeking removal may, at the expense of that shareholder, give notice
personally or by mail at any time up to twenty days before the date set for the
annual meeting.

                  (ii) If by a provision in the Articles of Incorporation the
holders of the shares of a class or series, voting as a class or series, are
entitled to elect one or more Directors, a Director elected in that manner may
be removed only by the applicable vote of the holders of the shares of that
class or series.

          (6) Regular Meetings:  Regular meetings of the Board of Directors or
              ----------------
any committee may be called by the President, a Vice-President, the Secretary,
or a director and may be held with or without notice at the principal place of
business of the Corporation or at such other place or places, either within or
without the State of Alaska, as the Board of Directors or such committee, as the
case may be, may from time to time designate.  The annual meeting of the Board
of Directors shall be held with or without notice immediately after the
adjournment of the annual meeting of shareholders.

                                       7


          (7) Special Meetings:  Special meetings of the Board of Directors may
              ----------------
be called at any time by the President, a Vice-President, the Secretary, or a

before the meeting.  Such notice shall include disclosure of the business to be
transacted and the purpose of the meeting.

          (8) Quorum:  A majority of the whole Board of Directors, or in the
              ------
case of meetings of committees of the Board of Directors the majority of the
members of said committees, shall be necessary at all meetings to constitute a
quorum for the transaction of business, and the votes of a majority of those
directors present at any properly called meeting at which a quorum is present
shall be sufficient to transact business.

          (9) Waiver of Notice:  Attendance of a director at a meeting shall
              ----------------
constitute a waiver of notice of such meeting, except where a director attends
for the express purpose of objecting to the transaction of any business because
the meeting is not lawfully called or convened.  A waiver of notice signed by
the director or directors, whether before or after the time stated for notice,
shall be equivalent to the giving of notice.

          (10) Registering Dissent:  A director who is present at a meeting of
               -------------------
the Board of Directors at which action on a corporate matter is taken is
presumed to have assented to the action taken unless the director's dissent is
entered in the minutes of the meeting or unless the director files a written
dissent to the action with the secretary of the meeting, before the adjournment
thereof, or shall forward the dissent by certified mail to the Secretary of the
Corporation immediately after the adjournment of the meeting.  The right to
dissent does not apply to a director who voted in favor of the action.

          (11) Executive and Other Board of Directors Committees:  The Board of
               -------------------------------------------------
Directors, by resolution adopted by a majority of the entire Board of Directors,
may designate from among its members an Executive Committee and other committees
of the Board of Directors.  Unless the number of directors of the Corporation is
less than three, each committee shall have at least two members, who serve at
the pleasure of the Board of Directors.  Each committee has the authority of the
Board of Directors, except that a committee may not

               (b) approve or recommend to shareholders actions or proposals
requiring approval by shareholders;

               (c) designate candidates for the office of director, for purposes
of proxy solicitation or otherwise, or fill vacancies on the Board of Directors
or any committee of the Board of Directors;

               (d) amend the Bylaws;

                                       8


               (e) approve a plan or merger not requiring shareholder approval;

               (f) capitalize retained earnings;

               (g) authorize or approve the reacquisition of shares unless under
a general formula or method specified by the Board of Directors;

               (h) authorize or approve the issuance or sale of, or a contract
to issue or sell, shares or designate the terms of a series of a class of
shares, unless the Board of Directors, having acted regarding general
authorization for the issuance or sale of shares, a contract to issue or sell,
or the designation of a series, authorizes a committee, under a general formula
or method specified by the Board of Directors by resolution or by adoption of a
stock option or other plan, to fix the terms of a contract for the sale of the
shares, a contract to issue or sell, or the designation of a series, authorizes
a committee, under a general formula or method specified by the Board of
Directors by resolution or by adoption of a stock option or other plan, to fix
the terms of a contract for the sale of the shares and to fix the terms upon
which the shares may be issued or sold, including, without limitation, the
price, the dividend rate, provisions for redemption, sinking fund, conversion,
voting or preferential rights, and provisions for other features of a class of

adopt a final resolution setting out all the terms of a series for proper
filing; or

               (i) authorize, approve, or ratify contracts or other transactions
between the Corporation and one or more of its directors, or between the
Corporation and a corporation, firm, or association in which one or more of its
directors has a material financial interest.

          A committee so appointed shall keep regular minutes of its meetings
and shall cause them to be recorded in books kept for that purpose in the office
of the Corporation.  The designation of a committee, the delegation to the
committee of authority, or action by the committee under that authority does not
alone constitute compliance by a member of the Board of Directors or the
committee in question with the responsibility to act in good faith, in a manner
the member reasonably believes to be in the best interests of the Corporation,
and with the care, including reasonable inquiry, as an ordinarily prudent person
in a like position would use under similar circumstances.

          (12) Remuneration:  No stated salary shall be paid directors, as such,
               ------------
for their service, but by resolution of the Board of Directors, a fixed sum and
expenses of attendance, if any, may be allowed for attendance at each regular or
special meeting of such Board of Directors; provided, that nothing herein
contained shall be construed to preclude any director from serving the
Corporation in any other capacity and receiving compensation therefor.  Members
of the Executive Committee may be allowed like compensation for attending
committee meetings.

          (13)  Loans to Directors:
                ------------------

                (a) A loan may not be extended to a director without the
approval of two-thirds of the voting shares. An employee or officer who is also
a director is considered a

                                       9


director for purposes of this section. A shareholder is not disqualified from
voting on a loan to a shareholder as a director because of personal interest.

                (b) A loan to a director and a loan secured by the shares of the
Corporation may not be made unless the loan would be permissible as a

mature.  The Corporation may not make a distribution to the Corporation's
shareholders, unless the amount of retained earnings of the Corporation

of the assets of the Corporation, exclusive of goodwill, capitalized research
and development expenses, evidences of debts owing from directors or officers or

                                   ARTICLE IX

                    Indemnification of Officers, Directors.
                    ---------------------------------------
                              Employees and Agents
                              --------------------

          (1) The Corporation shall indemnify any person who was, is, or is
threatened to be made a party to a completed, pending, or threatened action or
proceeding, whether civil, criminal, administrative or investigative, other than
an action by or in the right of the Corporation, by reason of the fact that the
person is or was a director, officer, employee, or agent of the Corporation, or
is or was serving at the request of the Corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise.  Indemnification may include reimbursement of expenses,
attorney fees, judgments, fines, and amounts paid in settlement actually and
reasonably incurred by the person in connection with the action or proceeding if
the person acted in good faith and in a manner the person reasonably believed to
be in or not opposed to the best interests of the Corporation, and, with respect
to any criminal action or proceeding, the person had no reasonable cause to
believe the conduct was unlawful.  The termination of an action or proceeding by
judgment, order, settlement, conviction, or upon a plea of nolo contendere or
its equivalent, does not create a presumption that the person did not act in
good faith and in a manner which the person reasonably believed to be in or not
opposed to the best interests of the corporation, and, with respect to any
criminal action or proceeding, the person had reasonable cause to believe that
the conduct was unlawful.

          (2) The Corporation shall indemnify any person who was, is, or is
threatened to be made a party to a completed, pending, or threatened action by
or in the right of the Corporation to procure a judgment in its favor by reason
of the fact that the person is or was a

                                       13


director, officer, employee or agent of the Corporation, or is or was serving at
the request of the Corporation as a director, officer, employee or agent of
another Corporation, partnership, joint venture, trust, or other enterprise.
Indemnification may include reimbursement for expenses and attorney fees
actually and reasonably incurred by the person in connection with the defense or
settlement of the action if the person acted in good faith and in a manner the
person reasonably believed to be in or not opposed to the best interests of the
Corporation. Indemnification may not be made in respect of any claim, issue, or
matter as to which such person shall have been adjudged to be liable for
negligence or misconduct in the performance of the person's duty to the
corporation except to the extent that the court in which the action was brought
determines upon application that, despite the adjudication of liability, in view
of all circumstances of the case, the person is fairly and reasonably entitled
to indemnity for such expenses that the court considers proper.

          (3) To the extent that a director, officer, employee or agent of the
Corporation has been successful on the merits or otherwise in defense of an
action or proceeding referred to in subsections (1) and (2), or in defense of
any claim, issue, or matter therein, the director, officer, employee, or agent
shall be indemnified against expenses and attorney fees actually and reasonably
incurred in connection with the defense.

          (4) Unless otherwise ordered by a court, indemnification under
subsections (1) or (2) shall only be made by the Corporation upon a
determination that indemnification of the director, officer, employee, or agent
is proper in the circumstances because the director, officer, employee, or agent
has met the applicable standard of conduct set out in subsections (1) or (2).
The determination shall be made by (a) the Board of Directors by a majority vote
of a quorum consisting of directors who were not parties to the action or
proceeding; or (b) independent legal counsel in a written opinion if a quorum
under (a) of this subsection is (i) not obtainable; or (ii) obtainable but a
majority of disinterested directors so directs; or (c) approval of the
outstanding shares.

          (5) The Corporation shall pay or reimburse the reasonable expenses
incurred in defending a civil or criminal action or proceeding in advance of the
final disposition in the manner provided in (4) of this section if

              (a) in the case of a director or officer, the director or officer
furnishes the Corporation with a written affirmation of a good faith belief that
he has acted in a manner that was in the best interest of the Corporation, in
good faith and with a degree of care, including reasonable inquiry, that an
ordinary prudent person in a like position would use under similar
circumstances;

              (b) the director, officer, employee, or agent furnishes the
Corporation a written unlimited general undertaking, executed personally or on
behalf of the individual, to repay the advance if it is ultimately determined
that an applicable standard of conduct was not met; and

              (c) a determination is made that the facts then known to those
making the determination would not preclude indemnification under this section.

                                       14


          (6) The indemnification provided by this Article is not exclusive of
any other rights to which those indemnified may be entitled under a bylaw,
agreement, vote of shareholders or disinterested directors, or otherwise, both
as to action in an official capacity of the person and as to action in another
capacity while holding the office.  The right to indemnification continues as to
a person who has ceased to be a director, officer, employee, or agent, and
inures to the benefit of the heirs, executors, and administrators of the person.
The indemnification powers of the Corporation shall be as broad as is allowed
under applicable law.

          (7) Upon the majority vote of a quorum of the Board of Directors, the
Corporation may purchase and maintain insurance on behalf of any person who is
or was a director, officer, employee, or agent of the Corporation, or is or was
serving at the request of the Corporation as a director, officer, employee, or
agent of another corporation, partnership, joint venture, trust, or other
enterprise against any liability asserted against the person and incurred by the
person in that capacity, or arising out of that status, whether or not the
Corporation has the power to indemnify the person against the liability under
the provisions of this Article.

                               Books and Records
                               -----------------

          The Corporation shall keep correct and complete books and records of
account, minutes of proceedings of its shareholders, Board of Directors, and
committees of the Board of Directors, and a record of its shareholders,
containing the names and addresses of all shareholders and the number and class
of the shares held by each.  The books and records of account, and minutes may

form within a reasonable time.  The Corporation shall make its books and
records, or certified copies of them, reasonably available for inspection and
copying at the registered office or principal place of business in Alaska by the
shareholders of the Corporation.  Shareholder inspection shall be upon written
demand stating with reasonable particularity the purpose of inspection.  The
inspection may be in person or by agent or attorney, at a reasonable time and
for a proper purpose.  Only books and records of account, minutes, and the
record of shareholders directly connected to the stated purpose of the
inspection may be inspected or copied.

has less than 100 holders of record of its shares, it shall be exempt from this
requirement.

                                       15


          (2) In addition to the financial statement required by (1) of this
